Need help with IPhone vocab sync

I posted this two days ago in user conversations to no avail. I can't get my vocab to sync with the new IPhone application. When I open the Chinesepod review app it shows no vocabulary words, when in reality I have thousands saved on Chinesepod. Since I bought the IPhone primarily to access Chinesepod, I'm really disappointed. Can anyone advise me what I am doing wrong? Bueller...anyone???
